To all whom it may concern.'

Be it knoivn that I, CHARLES W. MURPHY, a citizen of the United States,residing at Chicago, in the county of Cook, State of 4illinois, haveinvented new and useful Improvements in AutomobileeSignals, of which thefollowing is a specication.

ln handling automobiles on crowded thoroughfares, there has grown-up acustom in accordance with Which the driver of the machine, when about toturn his machine from its course,holds' out his arm on one side or theother of the machine ,as a signal that he'is about to turn the machinein the direction in which his arm is extended. The same signal is alsoused as an indication that the driver intends to slacken the speed otthe machine. ln either case, the signal is displayed as a Warning toother drivers following closely behind and also to drivers coming fromthe opposite direction, to traffic policemen, pedestrians and others. Inpractice, it is often inconvenient for the chauffeur to release hisholdy on the steering wheel and other parfts of the machine in orderthat he may ext-end his arm 1n the manner above set forth.V

\"\lt is the obj ect of the present invention to provide an automobilewith a signaling device, operative i'rom the drivers seat and adaptedfor indicating by means of suitable pai-.intere or semaphores acontemplated change in the course or management of the machine. To thisend the automobile is f :quipped with a pair of pivoted indicators orpointers provided with control mechaeasily operatedhy the driver' from aimmediately adjacent to the steering wheel of the machine.

ll' desired, the pointers or semaphores may be equipped with a smallelectric light, so that the signaling device will be effective in thenighttime as Well as in the daytime.

The details of mv invention Will be better .z understood by reference tothe following vdetailed description taken in conyunction with thedrawings forming a part of this spcciiication.

ln the drawings, Figure l' is a perspective view of one embodiment of myinvention,

showing the signal device attached to an automobile, which is hereindicated by dotted lines; Fig. 2 is a sectional elevation through themachine at the side of the steering Whee1;` Fig. Sis a rear elevation oithe Wind-guard, showing the mounting and con necting devices for thepointers or indicators. 'Fig'. 4 is a perspective view, showing indetail the light carried at the end of the pointer or semaphore.

In the construction shown, the signal device comprises two pointers orindicatorsl and 2, preferably in the shape of arrows and pivotallymounted respectively at 3 and 4 on suitable rigid supports. ln theembodiment hcre'shoivn, these supports are the side members of aWind-shield and the pivots 3 and el are located below the hinges of theshield, so that the top portion of the shield may b e dropped forwardinto folded position Without in any ivay disturbing the indicators 1 and2. Then in raised posi tion the hinged portion or' the shield concealsin large measure the indicators 1 and Q and protects them, as will bereadily understood.

Connecting rods or links and 6 have theirupper ends passed through andpivotally connected With the tail pieces of indicators 1 and 2 and serveas the actuating means whereby those indicators may be thrown intohorizontal position or into vertical position, as indicated 1n Fig. 1.The upper pivotal connection of these links is odset with respect to thepivots Band 4:, so that there may be no dead center when the indicatorsare to be moved.

The lower ends of links and 6 are connected respectively through cranks7 and 8 to a pair of horizontal drive shafts 9 and 10. The former issomewhat shorter than the latter in order that the control mechanism forthe driving shafts may be brought up at the sides of the steeringl post.Drive shaft 9 is actuated through a crank 11,

, keyed thereto and pivotally connected with a push-rod 12. Similarlydrive shaft 10 is actuated by a crank 13, moved through the medium of apush-rod 14. The push-rods 12 and 1li terminate respectively at theuppost.

Each of 4the drive shafts 9 and 'l0 1e pro-- vided Awith e. lcoiledSpring, i'nunhered re spcctively 20 and 21, one end of which is; iriniyattached to the shaft end the other end ci which is secured to esuitable coller 22 and 23 (Fig. 23) rigidly mounted on ai. suitable partof the automobile.

Normally, both pointers or indicatore stuud vertical und are held inthat position by a slight tension in springs 2() and 2l, But if thedriver of the machine intende to turn his nmchine to the left, he pushesdownward on knob 16 until the tapered projection l? passes through theslotted plete 18. The control rod 14 then drops or swings forwardsuficiently to insure e locking en gegernent between the projectionliend the plate 1S, preventing the return of the mechM enism to lieiniiiei position. The downward movement-of the push-rod 1.2i will turnthe drive ehei'u l() and liift the link (3,- thereby Swinging' theindicator 2 into e horiznntel p eition, es indicated in Fig. l.' Duringthe turning` movement of shaft l0 spring 2l is; iightened up. After thechauffeur has turned the corner and desires to restore the indiczitor toits normal or vertical position. it ir: only necessary for hiin iloreach down und lift or swing 'the push-rod fell high enough zo let theprojectiiiin 1li" slip by plete 18. The coil spring Ql will then snapthe nieelniniein heck to iis initial position und the indicator willreiuzn to normal.
